I couldn't stop myself, so I did a little research anyway. Obviously there are no men's rights group nearly as powerful as women's groups like NOW or you would have heard of them without having to do any search. There are a few fledgling organizations, though, and coincidentally they just had their 2nd annual National Men's Equality Conference in Washington DC a couple of days ago
http://www.trueequality.com/. I'm sure you all saw it covered on the evening news

. Also, here is a long list of men's rights groups with links to each
http://www.menweb.org/throop/orgs/orgs.html. It seems that many of these groups are primarily focused on the issues of father's rights. Here are some of the other men's rights issues that have been identified:
1) Family law: adoption, Ch*ld custody & support, divorce, paternity testing.
2) Employment: parental leave (another father's rights issue), sexual harassment (not sure if that means our being harassed or the presumption of guilt when we're accussed)
3) Education: reverse discrimination, Title IX (girl's sports get equal funding regardless of the amount of participation)
4) Legal: judicial bias (men are more likely to be convicted of false allegations of sexual abuse than they are for other crimes)
5) Military: conscription for males only (not an issue in this country with its all-volunteer army) Given all the reports of rape at various military academies, Tailhook, etc. this is not an area where guys should be the ones complaining. Although, did anyone else notice how the media went gaga over Jessica Lynch rather than all the male soldiers that were killed trying to protect her while she fumbled with her gun or the question of what a waif like girl was doing in a war-zone to begin with (there's a case of equal oportunity run amok).
6) Domestic Violence: Husbands abused by wives happens more than you would think and the reaction of authorities is way different when it does.
7) Media: I discussed this before
8 ) Health: circumcision as a form of male mutilation(I don't see the big deal there) and research funding for prostate cancer.
This last item is kind of interesting. I didn't realize that prostate cancer is the 2nd most common form of cancer in the US (skin cancer is first) and yet it receives about half the funding of the much less common breast cancer.
Finally, it should be pointed out that while there are no well-funded men's rights groups, like Ringo asked about, it should be kept it mind that "victimization of men" is a relatively new thing from a historical perspective whereas discrimination against women dates back pretty much to the beginning of our species. The women's rights groups started small too, way back in the beginning of the 19th century as the suffragette movement. Just as the that movement was small and lacking in political power in the beginning, so the much younger men's rights movement is small and lacking in significant organisation or influence at the moment. It remains to be seen what the future holds or whether these groups will gain any ground. The pendulum has swung the other way. Will it swing further to even more ridiculous heights on the other side? Perhaps. Many woman will argue that it needs to swing further nd I'm sure it does in many areas. But, it is hard to imagine it could ever get as bad for us as it was for women in this country during our early history or still is in many parts of the world (will men ever be required to wear burkas

?). One can only hope that eventually things will find some happy medium.
